10x 3.2v 280ah Lifepo4 Prismatic Battery Module - 1 Low

You can pick up from our Bensalem, PA location for free or we have excellent freight rates which include residential and lift gate service. We also have a shipping calculator at the bottom of this page to quickly estimate your shipping costs.

Only $47 per good 3.2v 280ah cell. Plus you get all the accessories as you can see in the photos.

Each module has 10x 3.2v 280ah cells in 10s1p configuration. 1 of the cells is lower voltage than the rest. So 9 cells in these modules are balanced with good voltage. The 1 low voltage cell is either fully discharged or very low voltage. That cell may have just been discharged from a faulty balancer but it could also just be a bad cell. There is no BMS however as you can see you can easily add a BMS to it since the balance lead wires are all there.

What appears to be a BMS in the 2nd to last photo is likely just the balancer with communication. The main negative connection does not run through that device so it likely just balances and/or communicates to another main unit. 

They are used and not capacity tested however we did confirm 9 out of 10 cells are still good. They were used in a backup power cabinet.

Module weight is approximately 154 lbs.

Dimensions are 9" tall x 8.75" wide x 38.5" deep

Module Fully charged - 36.5v (3.65v per cell)
Module Fully discharged - 25v (2.5v per cell)
Recommended max continuous charge and discharge rate - 140a

If you want to use this module for cell recovery, take a look at the 4th photo and zoom into the series busbar connections. You'll see the busbar raises up in between the cells. What most customers do is carefully, and at their own risk of course, dremel that raised connection with a flush cutting wheel. This would leave a nice size busbar tab sticking off each cell. Then they pry up that busbar tab a little, drill a hole, then make connections to the busbar with nuts, bolts, and ring terminals.

The main positive and negative connections on the outside of each module can be connected with bolts. We include the bolts but they are just not shown in the photo. If you wanted to reuse the face of these enclosures you can certainly use those connections.
